Did the interview, this morning. All in German, which went surprisingly well. Expectation was that we would exchange pleasantries in German, then switch to English for the remainder. Got complimented on my German actually, which prompted me to serve up the anecdote of that time when I was actually mistaken for Swiss by a Hamburger. Biel/Bienne is in the (German-speaking) Canton of Bern, right on the German/French language border and officially bilingual, but pretty much majority French-speaking in practice. Company is German-speaking, though, with some English thrown in for good measure. Should be interesting.
